Lucknow North assembly seat, which had been stronghold of the Bharatiya Janata Party for long before SP won the 2012 polls, is all set to witness keen contest among BJP, SP, BSP and Congress. In the 2014 Lok Sabha general elections, Lucknow Cantonment assembly segment had given a lead of 19101 votes to Rajnath Singh, the current Union Home Minister, over his nearest Congress rival Rita Bahuguna Joshi.
